Carbon frame version:  https://www.printables.com/model/486129

My goal is to make a micro fpv racer to use in my backyard to have fun with less troubles as possible.

It designed to host a 25*25 AIO board and caddx vista vtx.

If you will to use analog vtx or other digital system you just have to worry about making an adapter that has the external dimensions of caddx vista.

I printed the frame in polycarbonate and also petg and it can handle hard crashes but not on hard surfaces like concrete.

The electronic parts are well protected by the tpu canopy and the tpu support.

Hardware you need:

• 4x M2x12 screws to mount the electronics
• 4X M2 nuts
• 16x M2x6 screws for the motors

My configuration:

• Motors: T-Motor F1507 3800kv
• FC and ESC: MAMBA AIO F722 MK1 35A
• Vtx: Caddx Vista
• Camera: Caddx Nebula Pro
• Battery: 4s 850mAh

In the files section I added a zip file which contains all my gcodes.

The gcode of frame is to be printed in PC. I used this one: https://www.filoalfa3d.com/it/tech/573-3605-ALFALOY31-8057635590019.html#/11-colore-nero/30-diametro-175_mm/51-peso-1_kg

All other parts are printed with SainSmart TPU 95A.

Use heat to form the camera mount:
